FOLKE W. WESTON, OF NEW YORK, N. Y., ASSIGNOR TO F. WESEL MANUFACTURINGCOMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

REGISTER-HOOK.

To all whom it may concern Be it known that I, FoLKn WV. Wns'ron, acitizen of the United States, and a resident of, the borough of Brooklynof the city of New York, in the State of'New York, have invented certainnew and useful Improvements in Register-Hooks, of which the following isa specification, reference being had to the accompanying drawings,forming a part hereof.

The invention relates to printers plate holding means.

One of the objects of the invention is to provide a construction whichwill be simple, compact, e'flicient, strong and powerful.

Another object of the invention is to devise a construction comprisingin combination a base member having at least a slotted portion providedwith series of teeth arranged along the slotted portion, a movable plateengaging hook carrying member provided with an ear or ears which enterthe slotted portion of the base and a screw operating member for causingthe plate engaging member to be moved along said slotted portion. Thescrew member is arranged to mesh with the teeth above referred to andhas end engagement with the ear or ears. This screw is actuated by amember which extends between one of the ears and the screw and whichmember engages one end of the screw.

The improvements will be more fully described with reference to theaccompanying drawings, in which,

Figure 1 is a view in longitudinal section of a hook embodying theinvention. Fig. 2 is a view of the same in transverse section, the planeof the section being indicatedby the line 2-2 in Fig. 1. Fig. 3 is aplan view partly broken away, and, Figs. 4 and 5 are detail views of thescrew or adjusting member.

The register hook illustrated in the accompanying drawings is of theform or type shown and described in my application for Letters Patent,Serial No. 452,789, filed September 12, 1908, which form or type is notcompulsory so far as the present invention is concerned but simplyillustrative thereof. In this hook the base or block is yokeshaped beingprovided with arms 6 which embrace the traveling member or clamp a, saidarms forming therebetween an elongated opening or slotted portion.

ter is preferably I-shaped in cross section or end elevation (Fig. 2)being, as it is, provided with extended bearing faces above and belowwhich travel upon the top and bottom faces respectively of the side arms6 as the member a is advanced and retracted. The vertical members orears of the clamp a have journaled therein or therebetween the adjustingor propelling member 0 which in the present case is a longitudinallyextending screw engaging threads or teeth in the side members 6, thelatter being preferably solid throughout so as to form a strong andmassive hook. The screw is provided at one end with a bearing (Z whichmay fit loosely in the vertical member of the clamp a (Fig. 2), and atthe other end with a head or disk f (Figs. 1 and 5) which hasintersecting grooves in its outer face for engagement therewith of ahand operating member or tool g, as illustrated, to turn the screw. 7

From an inspection of the drawings it will be noted that the base 6 isprovided with slotted portion having at each side thereof alongitudinally of the slotted portion and that the screw member has endengagement with the vertically extending member or cars of the plateclamping or hook carrying It will furthermore be noted ber 9 passesthrough the opening in the hook carrying member a and extends betweenone of the vertically extending members or ears and the screw so as toengage the latter to actuate the same.

The jaw b is set well back upon the member a in order that it may beclamped over the edge of a plate and leave a very small margin. Such awconsists of two parts, one on one side of the clamp and the other on theother side, while between the jaws 1s an opening I) in the upper face ofthe member a, through which the hand operating member or tool 9 may beinserted to reach the head of the screw, said opening being insubstantially the same plane as the head.

Besides being undercut upon the forward edge so as to overhang theplate, the jaw 72 is also undercut along its rear edge (Fig. 1).Moreover, the whole clamping member a is symmetrical so that it may bereversed,

thus presenting the rear edge of the jaw in position for clamping aplate. The rear edge of the jaw, as will be seen, is relatively near theend of the clamping member, so that it may be moved much nearer theforward end of the clamp than the forward edge of the jaw, and thus thereversibility of this member increases the adaptability or utility ofthe hook as was stated herein before.

It will be understood that various embodiments may be had of the presentimprovements, and hence the invention is not limited to the form or typeof hook or to the features of construction shown and described herein.

I claim as my invention:

1. The combination of a base having an elongated opening provided withteeth on the opposite sides thereof, a longitudinally movable memberhaving a plate engaging jaw and spaced ears entering the elongatedopening between the teeth and a screw member of a proper size and shapefor the outer portions thereof to engage said teeth, said ears beinglocated at the ends of the traveling member and the screw member beinglocated endwise therebetween, said movable member being provided with anopening for an operating member or tool which when in the opening isbetween one of the ears and the screw member and engages one end of thelatter.

2. In a register hook, the combination with the base or block of atraveling member provided with ears, screw means located between saidears to move the traveling member longitudinally, said traveling memberhaving an upper face with a transverse elongated opening therein toprovide access for a tool which is to engage between the ears the screwmeans for operating the same and also to permit a swinging movement ofthe tool when it is operating the screw means, and a jaw on thetraveling member to engage a plate, the screw means being carried by theears and movable longitudinally with the traveling member, the earsbeing arranged longitudinally relative to the screw.

3. The combination of a base having a slotted portion the side walls ofwhich are provided with sections of screw threads, and a travelingmember provided with a jaw to engage a plate and vertically extendingears at the opposite ends of the traveling memher which ears enter theslotted portion, said ears having therebetween a longitudinallyextending screw operating member which engages the sections of screwthreads in the walls and an opening through the top of the travelingmember through which means for causing the movement of the screwoperating member passes, said means engaging the screw operating memberbetween the ears which are located at the extremities of the screwoperating means.

. 4. The combination of a base having an elongated opening thereinprovided with screw threaded sectlons, a clamplng member having earsentering said opening, a longitudinally extending operating screwengaging the screw threaded sections of the base and a longitudinallyextending bearing, said screw located between the ears which are at theends of the screw, said screw also being held in place by the hearingwhich extends between the screw and at least one of the ears.

5. The combination of a base having a slotted portion provided withteeth on the opposite sides thereof, a longitudinally movable memberhaving a plate engaging jaw and a vertical member entering the slottedportion between the teeth, and a screw engaging the teeth and having endengagement with the vertical member, said movable member having anopening in and extending through the top portion thereof for anoperating tool or member which engages the end of the screw that engagesthe vertical member.

6. The combination of a base having a slotted portion providedlongitudinally thereof with a series of teeth, a hook carrying membermovable along said slotted portion and a rotatable screw operatingmember whose axis extends longitudinally of said slotted portion, thehook carrying member having a printers plate engaging hook at the topthereof and a vertically extending member or ear which enters saidslotted portion, the screw being in engagement with said teeth and theend of said screw member being in engagement with the verticallyextending member or ear, the hook carrying member being provided with anopening at the top whereby the screw can be actuated by a screw engagingmember which extends between said vertically extending member and saidscrew.
